Description
Technical field
Control cylinder plunger rod to stretch by adjusting air pressure the present invention relates to one kind, realize the dress of seat step-less adjustment height
Put.
Background technology
Using the flexible seat to adjust height of seat of cylinder plunger rod, in the market has been merchandised for many years, because of seated user's body weight
Difference, the height regulation of seat is still difficult satisfactory：The excessive person of body weight can make seat minimize position, and the too small person's difficulty of body weight makes seat
Chair declines and is in highest order, average-sized man and each in an intermediate position with the difference adjustable height of its body weight, rear to develop again
Use and use manually handle handle, centre position is positioned with modes such as latch or friction locks, but this is a kind of " hard
Fall ", cushioning effect is small, component damage is big, easily break down and also can only stepping regulation, it is impossible to realize step-less adjustment.
CN201020612048.5 discloses " seat lifting resets air-leg ", is to be oriented to reset fortune in barrel to improving piston rod
Stability during row proposes improvement idea；CN201320627640.6 discloses " a kind of lifting seat air pressure rod ", is to gas
The firmness of cylinder suggests improvements with flexing resistance.Through retrieval and market survey, it is not yet found that closing to the stepless of height of seat
Regulation is that the report and material object of the device controlled by air pressure appear on the market.
The content of the invention
Produced the technical problem to be solved in the present invention is to provide a kind of air pressure of cylinder type lifting seat and adjusting means.
The technical problem is solved to adopt the following technical scheme that：
Resistance in the air pressure generation of this cylinder type lifting seat and adjusting means, including cylinder, the spring at cylinder bottom, cylinder
Buddhist nun hole and tracheae, are characterized in that high pressure tank one is terminated with overflow valve and breather cheek valve, reversal valve is connected with cylinder, high pressure storage
The breather cheek valve and air pump of gas tank are connected with tracheae, and air pump is communicated by breather cheek valve with air, and air pump extension bar dissociates
The gear for being provided with rack on section face and engaging, the circumferentially fixed rotating shaft in gear centre is rigidly connected with chair back rack, gear
Rotating shaft two ends bearing is installed, its bearing block is fixed on seat board, is provided with stage clip and seat board on rear side of chair back rack, reversal valve is
Have three air pipe interfaces on 3-position-3-way hand-operated direction valve, the reversal valve, by tracheae respectively with cylinder, high pressure tank and air
Have what can be led to and close by rotation or three valve ports of slidable adjustment and three air pipe interfaces in connection, 3-position-3-way hand-operated direction valve
Valve element.
Air pressure in described high pressure tank is 0.4-0.6Mpa.
The beneficial effects of the invention are as follows：The height of seat can by seated user the need for realize step-less adjustment, replaced by air pressure adjustment
Mechanical adjustment is changed, resiliency is good, seated user is comfortable, and component damage is small, service life is long.
Brief description of the drawings
Accompanying drawing is present apparatus structural representation
Embodiment
The present invention is with reference to embodiment and is described in detail referring to the drawings：Referring to accompanying drawing,
In the air pressure generation of this cylinder type lifting seat and adjusting means, including cylinder 2, the spring 1 at cylinder bottom, cylinder
Damping hole 3 and tracheae 8, high pressure tank 18 1 are terminated with overflow valve 6 and breather cheek valve 9, and reversal valve 7 is connected with cylinder 2, high
The breather cheek valve and air pump 11 of gas tank is pressed to be connected with tracheae, air pump is communicated by breather cheek valve 10 with air, and air pump is stretched
Rod is provided with rack 12 and the gear engaged 13 on free section face, circumferentially fixed in the rotating shaft 17 of gear centre and chair back rack
14 are rigidly connected, and the rotating shaft two ends of gear are provided with bearing, and its bearing block is fixed on seat board, and stage clip is provided with rear side of chair back rack
15 and seat board 16, reversal valve is to have three air pipe interfaces on 3-position-3-way hand-operated direction valve, the reversal valve, by tracheae respectively with gas
Cylinder, high pressure tank and air connection, have in 3-position-3-way hand-operated direction valve can by rotate or three valve ports of slidable adjustment with
Three logical valve elements with closing of air pipe interface.
Air pressure in described high pressure tank 18 is 0.4-0.6Mpa.
Seat with the present apparatus no matter when taking or unmanned when sitting, if in the control cylinder 2 of reversal valve 7 air pressure with
Atmospheric pressure is communicated, then when adding seated user's body weight again because bearing chair gravity or chair on plunger rod 5, seat support is bottomed out, and can also be led to
The air pressure crossed in the control cylinder 2 of reversal valve 7 is communicated with high pressure tank 18, and seat support rises to highest in the presence of gases at high pressure
Position；When the seat needs to position in any controllable scope, reversal valve need to only be closed, make air pressure in cylinder neither
Communicated with air, can not with high pressure tank phase general rule yet.The pilot seal part 4 of cylinder body upper end and the air pressure in cylinder and in plunger
It is completely enclosed, due to the big face thereon of gas pressure area below plunger lower head, and the difference of its two sides gas pressure power with
The balance of making a concerted effort of chair weight and people's weight, chair height is just fixed.For the big people of weight, the decline that plunger rod can be micro, in cylinder
Gas compression and add upward reaction force, dynamic balance is voluntarily finely tuned and is positioned；Due in plunger lower head and gas
There is damping slotted eye 3 between cylinder inner surface, plunger rod raising and lowering speed is become even, the spring 1 of cylinder bottom enters
One step reduces impact of the plunger to cylinder bottom.
Reciprocating inflation of the hyperbar of high pressure tank from the inner carrier of air pump 11, and its reciprocating motion is by tooth
Wheel 13 is rotated to caused by the left and right push-and-pull of rack 12, this push-and-pull is again because seated user back is to the chair back 14 repeatedly clockwise and anticlockwise
Cause with the pressure of spring 15 and putting.
Seat with the present apparatus, no matter body weight size, as long as being transferred to seated user's body weight and seat (in addition to chair leg portion) weight
The pressure balance of the gravity and cylinder interior gas of sum, you can any position positioning in range, realizes buffering, nothing
The height regulation of level.
